APPARATUS FOR THE MANUFACTURE OF PLATE OR BLOCK ICE.

SPECIFICATION forming part of Letters Patent N 0. 710,656, dated October7, 1902.

Application filed May 31. 1902a Serial No. 109,634. No model.)

To all whom it may concern.-

Be it known that I, EDWARD ISARRATH, a citizen of the United States,residing at the city of Philadelphia, in the county of Philadelphia andState of Pennsylvania, have in vented certain new and usefulImprovements in the Manufacture of Plate or Block Ice, of which thefollowing is a specification.

My invention has relation to the manufacture of plate or block ice in apure crystallike state free from air-bubbles and needles.

The principal objects of my invention are, first, to provide suitableapparatus for manufacturing artificial plate or block ice fromconstantly-flowing water by means in which the water to be frozen isdelivered to a container and stilled and overflows onto an artificialfreezing platform or medium and then upon successive strata of iceformed thereon until a plate or block of ice has been built up bysuccessive accretions, and, second, to provide suitable apparatus foreconomically and efficiently carrying out the said invention of formingartificial plate or block ice.

My invention, stated in general terms, consists of an apparatus formaking artificial plate or block ice in substantially the mannerhereinafter described and claimed.

The nature, scope, and characteristic features of my invention will bemore fully understood from the following description,taken in connectionwith the accompanying drawings, illustrating a series of forms ofapparatus for carrying out my said invention, in which- Figure l is aview, partly in longitudinal central section and partly in elevation, ofone form of an apparatus for carrying out my said invention of makingartificial plate or block ice; and Figs. 2 and 3 are similar views oftwo other types or forms of apparatus for carrying out the same.

Referring to the drawings, A in Fig. 1 represents one form of freezingmedium or plate, contisting of a hollow rectangular or other shapeplatform a, through which a freezing fluid, as brine or ammonia, from asuitable source (not shown) is permitted to constantly flowtherethrongh. Arranged adjacent to one end of the hollow platform ormedium a and preferably abutting against the same is a container orreceptacle a, one portion of the wall a of which container or receptacleprojects above the opposite wall a of said receptacle or container forholding a volume of water continuously supplied thereto from a suitablesource (not shown) through the inletpipe a, having a regulating-cock a.The water enters the receptacle a below the upper surface of theplatform or medium a and constantly flowing through the inlet-pipe aunder more or less pressure from the source of supply spreads out withinthe container or receptacle a and in rising therein is stilled to thepoint where it overflows onto the freezing medium A and so continues toflow over successive strata of ice formed on the freez ing medium untilby successive accretions of ice formed therefrom on the medium there hasbeen built up an artificial plate or block of ice of the requireddimension. The force wit h which the Water flows into the receptacle acan be readily regulated by the cock a The water flows into thereceptacle and by expanding or spreading out is stilled, so that itoverflows from the container quietly over the said medium A. At the leftof the freezing medium A is located a ledge B for catching and directingany surplus Water from the ice-forming medium. This surplus water flowstherefrom into a suitable receiver (not shown) for use over again, or itmay be discharged into a waste-receptacle, if preferred.

In Fig. 2 the freezing platform or medium A is provided internally withembedded tubes or pipes I), through which the freezing media by acirculatory system passes for bringing and maintaining the surface ofthe platform into a condition for freezing water passing over the sameto form ice.

In Fig. 3 the platform or medium A is internally provided withrectangular-shaped tubes 1), alternating with contiguous solid blocks 11Through the tubes 1) the freezing media is circulated for preparing theplatform or medium A for ice-making.

The ice formed in the manner hereinbefore explained is crystal-like,free from air-bubbios and needles, and is made in much less time thanhitherto it was thought possible to make plate or block ice and of a fargreater thickness and uniformity in a given time.

Having thus described the nature and objects of my invention, what Iclaim as new, and desire to secure by Letters Patent, is

1. An apparatus for manufacturing artificial plate or block ice fromconstantly-flowing water, comprising a platform, a freezing mediumarranged beneath the platform, a source of flowing-water supply, meansfor receiving' and stilling the water from said supply and an outlet ordelivery from said means located adjacent to one edge of the upper faceof said platform and arranged to permit the stilled water to flow infilm form over the platform, substantially as and for the purposesdescribed.

2. An apparatus for manufacturing artificial plate or block ice fromconstantly-flowing water, com prising a platform arranged insubstantially a horizontal plane, a freezing medium located beneath theplatform, a container or stilling-chamber arranged at one side of saidplatform, a discharge from said container located in alinement with theupper face of the platform, in combination with means for introducingconstantly-flowing water into said container below said discharge.

3. In an apparatus of the character described, a container orstilling-chamber having an outlet or discharge, a platform forming acontinuation of said outlet or discharge and arranged substantially in ahorizontal plane in alinement with the outlet, a freezing medium locatedbelow the platform, said container extending below the freezing mediumand platform, and means for introducing constantly-flowing water intosaid container below the discharge therefrom, all arranged so that saidwater is first stilled in the container and thereafter permitted tooverflow in film form therefrom upon the platform.

In testimony whereof I have hereunto set my signature in the presence oftwo subscribing witnesses.
